As part of a large-scale cost-effective project of decentralisation and modernisation of energy management in Buzuluk, a.s., SEVEn Energy, s. r. o. carried out consultancy services in two stages in the preparation and implementation of energy savings measures, verification of technical solutions and solution parameters for the first stage and verification of economic and energy benefits for the investor. Our company also provided a conceptual design of the composition of the second stage of the project with regard to the analysis of the conditions for obtaining an investment grant. The second stage of the modernisation was thus supported from the 1st call of the Energy Savings Programme in the context of OPPIK programme. This was followed by a tender for a building contractor in which the supplier's participation in the later operation of the energy management in the form of a seasonal efficiency guarantee was applied to the investor. The entire modernisation was successfully completed in August 2017.
